Trying to get government hogs at the trough to slim down is Quixotic at best.
Probably never happen.
I truly believe there is a good chance that Obama is determined to make the nation default - though all experts know that is not necessary even without a deal.
Then, watching the world-wide (and national) earthquake from a US default he will do two things:
Declare a national emergency and dictatorial powers (which are already in place); blame the Republicans for the default with full media support hoping to effectively neuter the Repubs forever.
And a small possibility of taking legal action against Cruz, et al, even imprisoning them.
Of course I hope I am wrong.
But note that I did predict this a real possibility.
What would conservatives and Republicans do?
Nothing. Whine and wimper.
